And who are. It has a while. You. I thank you. Why. And who knew what. He has. Or why I'm you. Haven't heard about the wonderful thing for me. Yep that my father gave me a set of cards you want to see you take it from me on that rely on the job the way you are. Let's go. Here we are. You. A lot talk a what's on your mind now that my friend knew the want you to put him through the works. Why man you still run on sixty. We'll have to bet feel up to ninety. Open your mouth you. Come right along with me. The you. Are. Not talking let's put on an act for Miss him follow a slew. Of. Yeah. You. Really rare one. Minded who have a motion picture camera which is taking pictures through this window we use a soundproof moves when it's clear was it keeps the camera noise away from the microphone the camera is operated by a motor which runs exactly the same speed as a motor in the Sound Machine. Lulu It's hot in this movie. Let's get out on the set again and I was how the sound is picked up by the microphones on the stage sound waves are picked up by this wonderful mechanical air the microphone which is really a glorified telephone transmitter this microphone changes the sound waves into Aleck tickle a vibration which are amplified here and send along these wires to the mixer room the sounds from the stage microphones are mixed here so that the statue for the action in the production. Mr McNair's these actors through this window and hears them only through this current. Flow. Goal. Now that we've got the sound right. I was show you how it's amplified. Get ready for. The power from the microphones is amplified about ten million times by these vacuum tube making the voyage current strong enough to operate the machines that photograph the sound so you follow me. This is the machine that is used to record the sound on film. This sounds sound is traveling at the same rate of speed as the picture found in the camera though the light bout has to thin metal strings stretched across this tiny slit on one side of the sled. The strong life while on the other is a film moving at exactly the same speed as the picture camera in the studio the greatly Apple a five voice current passing through these tiny light bows strings move them to classes a gather are further apart. Thus changing the size of the site. Therefore the light berries as it passes through this rapidly changing opening leaving a true photographic record of the voice currents on the film. Simple illness. Now let's look at the films after they've been developed. Well here we are here are two negatives developed. The next step is the print these two negatives onto a third piece of film. Will print the sound record first and then the picture record. Here we have a completed sound praying and we are now ready for projection. This is the picture and sound projector. One motor drives both the picture and sound equipment saying Let me illustrate this with a simple diagram this lamp illuminates the soundtrack on the film the light from the lab classes through the slit throwing a very narrow line of brilliant light on the soundtrack as the film runs. Right the marks on the soundtrack cause the light to increase and decrease this light in turn causes the current through the photoelectric cell to increase and decrease. Bus reproducing the electric vibration first created by the sound wave the current from the photoelectric cell is stepped up by the amplifier and then this amplified current is carried by wire. Along right through on the mystery and. The say the connect with a loudspeaker. This is a typical layout of the stage that was to harness behind the screen the receivers connected to the heart and convert the electrical vibrations back in the Sound plays exactly the way the telephone receiver operates so that while the picture is being shown the sound which was recorded is reproduced in step with the picture. Of. The screen is full of small holes so that the harnes Maybe place behind the screen to let the sound through this gives the illusion that the sound is coming from the image of the speaker. Talking they're going to your Q Your next onscreen by music and go try on is no more you. Write. Her a. Pop pop pop pop music machine when I know I know. Ok doing his stuff I can say for right there where you got me. You. Know what you. Already know you. Look years Marty if you must stay on the screen with me. Suppose we get together was a little close harmony what he is saying hello. You relate you. You. You go. You. Know. Who's a. News.
